BLM 117
Bitumen-SBS Rubber Based
Elastomeric Liquid Membrane
Description
BLM 117 is a solvent based, bitumen-SBS rubber content, single component ready to
use elastomeric liquid membrane that used against to water and moisture. After evaporation
of solvents it contains, BLM 117 adheres firmly on the substrate and forms an elastic
waterproof layer.
Fields of Application
• In base of buildings against ground moisture and leaks.
• In retaining and curtain walls, galleries, drainage and piles.
• In terrace roof, balconies, water channels and gutters, bridges, viaducts on conditions that
BLM 117 is applied under the coating and protected.
• In external isolation of pools against water and moisture.
Features and Benefits
• It is easy to apply and ready to use.
• Creates a seamless isolation layer.
• Elastomeric.
• Applied as cold. Does not require heating and thinning.
• Quick dry.
• Applied on pressurized water resistance areas with a reinforcing materials such as
geotextile, fibermesh.
Application Procedure
Preparation of Substrate
Application surface must be dry, clean, clean off materials which prevent bonding, such as
dust, oil, rust and removed loose pieces. Sharp tips and horizontal/vertical joints which are
suitable cracking should be chamfered with PH 55. Big pores and cracks should be filled
with REPAMERK 1 or REPAMERK 301 repair mortar.
Application Method
BLM 117 is applied only onto the side exposed to water (positive insulation). It is ready to
use, it does not need heating or thinning. It can be applied by brush, roller, rake or airless
spray with at least two layers. Primers should be applied on the surface to provide excellent
adhesion, avoid dust and improve durability. B PR 101 is recommended for non-metal
surfaces, B PR 102 is used for metallic surfaces as primer. Although BLM 117 is a fast drying
type of solution (2 hours approximately), it is recommended to wait 24 hours before applying
a second coat. Reinforcing materials such as polyester felt, geotextile, fibermesh and
reinforcing fabric can be used to provide better durability against higher pressure. ALUCOAT
should be applied as topcoat to obtain solar protection and aesthetic look on the roof which
are continuously exposed to outdoor conditions and close the traffic.
Consumption
0,600 kg/m 2 for each layer. Recommended at least 2 coats application.
